Customer opinion - 4 stars out of 5
useful book with limits

If you ever had to program a complicated numerical algorithm, such as SVD decomposition, Bessel functions, eigensystems or Fourier transform, you will know how useful this book is. All those problems, and many others, are presented, the theory is explained and the full code of a routine, which solves it, is given. This version brings the codes in C++, but there are versions for Pascal, FORTRAN 77 and Basic. If you need any routine, you just have to "cut and paste" it from the book into your program.

Brillant ideas and formulas - This book is great.

I have been working with spreadsheets for about 15 years and thought that I knew all about it. This book has shown me some new tricks and techniques that have saved me time and allowed me to avoid writing VBA Code. Anything by Walkenbach is top notch.

! Concise && ( not very good with the examples)

If you're like me, and you're shopping for a book, you immediately start reading the negative reviews and work upwards. So I started reading the reviews and read through them all, bought the book despite the many negative, and frankly, snippish comments made by many reviewers and decided that I need to respond.
Many say that the examples are convoluted, or that he focuses on obscure language references. One says the book starts quickly with a discussion of the splice function. The first mention of splice is on page 355, which I certainly don't define as 'quickly'....
Others say that there are no examples, or they are not explained clearly, but there's a short sample program right on page 18, and then 4 pages are devoted to analyzing the program and how it works. Further review through the book shows many small examples, especially in the sections that outline the core functions of Perl, and the core modules of Perl.
Others come here and criticize Perl the language, and use this as a platform for their own advocacy of other languages. This is just silly. If you're interested in Perl, or you've been using Perl and you want to know more, buy this book. In the universe of computer programming, every language choice you make is controversial, and subject to debate, and just because some reviewers do not like Perl the language, it does not mitigate the quality of this book.
That all being said, and debunking the frankly lousy reviews, I'll caution that this is NOT for beginning programmers, or people with limited technical knowledge. O'Reilly knows this, and anyone who has read this book should know this too. There is a book called 'Beginning Perl', also from O'Reilly, and written by one of the other top minds in Perl. It is easy to follow, provides many concrete examples and is where a beginning programer should begin. If you have a technical background, you will probably be able to start with this book, though Learning Perl is still worth reading.
What this book provides is not only an exhaustive guide to the language of Perl, and it's abilities, but also insight into it's design, the decisions of the creator of the language (Larry Wall, the main author of the book created Perl), and the major philosophy behind Perl.
This is a valuable reference and worth having.
This is the book that I turn to when I have Perl questions.
And this book is worth every penny I spent to get it.
